A radome for an antenna is provided as a composite of an isotropic outer layer and a structural layer of foamed polymer material. The composite is dimensioned to enclose an open end of the antenna. The radome may be retained upon the antenna by a retaining element and fasteners. The outer layer may be a polymer material with a water resistant characteristic. The structural layer may project inward and/or outward with respect to a plane of the seating surface of the radome.

A radome for an antenna assembly includes a plurality of radome segments, each of the segments including a structural layer and an overlying outer layer, each of the segments further comprising a first radial side face, a second radial side face, and a perimeter section. The plurality of radome segments is assembled such that the first side face of each radome segment abuts the second side face of another radome segment to form a fully assembled radome, and the perimeter sections of the radomes together form a perimeter of the radome.

An apparatus comprising an enclosure for an antenna arrangement including physically integrated parts including a first part of relatively dense, injection moldable plastic and a second part of less dense, injection moldable plastic. The first part and the second part are contiguous.

A radome for an antenna is provided as a composite of an isotropic outer layer and a structural layer of foamed polymer material. The composite is dimensioned to enclose an open end of the antenna. The radome may be retained upon the antenna by a retaining element and fasteners. The outer layer may be a polymer material with a water resistant characteristic.

A radome is provided and includes a first layer of low density polymer (LDPE) through which electromagnetic radiation is transmittable, a second layer of LDPE foam through which the electromagnetic radiation, having passed through the first layer, is transmittable, a third layer of LDPE through which the electromagnetic radiation, having passed through the first and second layers, is transmittable and adhesive layers respectively interposed between the first and second layers and between the second and third layers.

Multi-layered articles or products comprising layers of filled polymer compositions, methods of making and applications or uses thereof.

The present application relates to a polycarbonate composite article, a preparation method therefor, and use thereof. The polycarbonate composite article includes a foamed polycabonate layer and a non-foamed polycarbonate film layer on the foamed polycarbonate layer. The polycarbonate composite article according to the present invention has a reduced weight and improved signal penetration performance, and can be used as an antenna housing.

Exemplary embodiments are disclosed of low dielectric, low loss radomes. Also disclosed are materials for radomes according to exemplary embodiments.
